Additional safety guidelines when using Lithium Polymer (Lipo/Lipoly) batteries;

Charging of Lipoly batteries will be done on or in a non-flammable surface or container out of the boat. Some suggested methods are, fireproof container, baking dish, bricks, clay pot etc.

A suitable fire suppressant or containment vessel will be mandatory in any area Lipoy batteries are being charged. The best and most cost effective fire suppressant is dry sand. A properly rated extinguisher may also be used. It will be the contestants responsibility to provide their own fire suppressant if charging is done in an open environment.
